I'm going to install my Spohn performance tubular front a-arms with spring boxes on Monday. Where should I mount the bumpstops on the car? Anyone done this yet? A pic perhaps?
Thanks.

 

Mount the bump stop on the k-member

 

Please post pics when its done.Ive been wanting to get these.....

 

I would't mount them anywhere where they put a load on the control arm... those tubular deals can't take a point load like that

 

Ground control sells bumpstops that go over the strut shaft.

 

I'm not sure which ones ground control sells, but pretty much the best stuff out there along those lines are the Koni sylasto (sp?) shaft bump stops...

 

These:

they're similar, the only pic of the koni's I can find is in this PDF:

Thanks guys, very helpful. I have even been planning on putting Konis on my car. The Ground control stuff looks good for now though. Whatever I can get my hands on most likely.

 

I'm in the process of installing the Spohn tubular A-arms and new struts/springs myself, and was wondering if you guys had any reccomendations on the firmness/size of bumpstop to order? The struts & springs are Tokico HPs.

 

Talk about timing.I just got these same A-arms from a member here today.I was gonna find some way to re-mount the bump stops on the cross member when i received this notice.Those Gr.control stops look very nice.I was thinking of getting the firm(rated) stops.Ive already got the G.C.weight jack set-up Fr/Rr.If anyone has already done this though.Id be helpful if you could give some info(if you went with the G.C. stops).BTW.Id like to give a big THANK YOU to matt formula for the great deal on the spohn arms.

 

I went with the ground control ones and have had no problems. I pulled my receipt for a part # but it just said "bumpstop". Make sure they give you ones for a 3rd gen and not a 4th (they are different, won't work, and I have a free set sitting in my spare parts pile)!!

 

Thanks.do you know why they have a 10-14mm set & a 19-24mm set(s).Is that refering to height or ?.What do yours look like(shaped).

 

The 19-24mm is for a strut. Mine are the ones on the far right in there pic (19-24 semi-linear-firm).

 

Great,those are the ones i was looking to get,Thanks for the help.

 

Same here. Just placed my order. Thanks guys!

 

9.9101 All purpose bump stop for control arms, traction bars & leaf springs. Designed to be easily trimmed. 2 1/8" tall, 2" dia. 2 per set

Actually these are what I used, I trimmed the first three layers off and mounted them to the frame.
